I must admit I'm finding this fun to use. I've been noodling away in a coffee shop this morning (via AirPods obviously, I'm not one of those speakerphone idiots) and it's surprisingly easy to pick up and start playing.
It's clearly no way near being able to replace a studio setup, and never was, but as a sketching tool to put something together that can be opened in Logic, ready to edit with all the bells and whistles, it's really quite useful. Especially for version 1.
I won't use it all the time, probably more for one-off subscriptions here and there when travelling or on holiday.
